MJPEGOIP-HDE Motion JPEG Over IP – HD Video Encoder Subsystem

This Video Over IP Subsystem employs JPEG compression and RTP/UDP/IP encapsulation to enable the rapid development of complete motion JPEG video streaming products. Hardware reference designs and customization services complete the solution.

The subsystem uses CAST’s JPEG-E-S, JPEG2RTP, and UDPIP IP cores. Flexible interfaces allow easy integration of video and network controllers; the cores’ AMBA® AXI4-Lite™ slave interfaces allow a host processor to access all control and status registers. An optional custom logic module allows standalone, processor-free operation and provides access to control and status registers via UDP packets. Video and stream data are transferred among the subsystem’s modules using AXI-Stream, making removing or adding modules straightforward.  

The produced stream can be decoded using Motion JPEG-compatible software viewers (e.g. VLC).


The MJPEGOIP-HDE Subsystem is suitable for live streaming in broadcasting, surveillance, industrial, defense, and medical applications. The platform consumes significantly less energy than software-based solutions, making it ideal as a compression coprocessor in battery-operated devices with video streaming capabilities.

Customization Services

CAST can integrate the MJPEGOIP-HDE subsystem with your choice of video-in, and network controllers, and map it to Xilinx or Altera FPGA boards offering sufficient resources. We can also modify the subsystem to support multiple video channels, or different CAST compression cores.
